Engineered for extreme sub-zero temperatures, heavy-duty cycles, and explosion-protected environments across Norway's fjord industrial clusters and offshore rigs.
Norway is at the forefront of the global green transition. The national target of cutting greenhouse gas emissions by 55% by 2030 puts unprecedented pressure on heavy industries—such as mining, maritime shipping, subsea mineral exploration, and petrochemical extraction—to replace inefficient power systems with highly reliable, green-optimized electric motors.
Our heavy-duty mining and explosion-proof motors are designed to operate under strict Arctic conditions (sub-zero ambient temperatures down to -40°C), while maintaining absolute structural resilience. From mainland iron ore mines in Kirkenes and Rana to deep offshore oil and gas production platforms in the North Sea, the demand for ATEX, IECEx, and DNV GL certified electric drives is higher than ever.
By offering superior energy efficiency classes (up to IE4 and IE5) and integrated VSD (Variable Speed Drive) solutions, we help Norwegian industrial operators dramatically decrease their operational carbon footprints, protect their personnel in explosive gas and dust environments, and achieve long-term sustainability targets.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized international distributor of Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), Wolong has achieved rapid global expansion. Today, the group operates 3 primary manufacturing bases, 39 state-of-the-art factories, and 3 global R&D centers.
Wolong’s global brand strategy has transformed it into an undisputed technology leader in motors and control systems. Its technical competence spans across low, medium, and high-voltage AC/DC electric motors, explosion-proof systems, and high-efficiency permanent magnet drives.
Through close synergy with internationally renowned century-old brands under the Wolong umbrella, we ensure that every motor shipped to Norway integrates cutting-edge engineering pedigree with reliable global supply chain networks.
Wolong's strategic acquisitions bring together the finest European design traditions and high-scale manufacturing efficiency.
To establish itself as the premier global manufacturer of AC motors & drives, Wolong undertook major strategic international acquisitions over the last two decades:
Acquired in 2011, ATB is one of Europe's top three motor manufacturers. It includes legendary brands such as Morley (underground coal mining motors with a 130-year history of quality and power) and Laurence Scott (custom low-starting-current generators and naval propulsion motors).
A venerable pioneer in low, medium, and high-voltage AC electric motors. Famous for the "W" and "10" series energy-efficient motors designed specifically for operation in harsh chemical, hazardous, and offshore maritime environments.
Established in Germany in 1882. Schorch sets international standards for heavy-duty, highly customized driving systems in petrochemicals, oil and gas, steel production, ship propulsion, and tunnel ventilation complexes.
OLI Vibration Motors: Since 1999, Wolong has integrated OLI's world-leading vibration motor technology and Ex vibration sensors into its portfolio, securing dominant global market share.
Nanyang Explosion-Proof Group (CNE): Acquired in 2015, CNE is China's largest scientific research and production base for explosion-proof electric motors, delivering low-voltage asynchronous and high-voltage ex-proof designs for oil, coal, defense, and nuclear industries.
General Electric (GE) Commercial & Industrial Motors: Acquired in 2018. The integration of GE's industrial motor business added unparalleled experience in serving American and global heavy industries with low and medium voltage drive systems.








For Norwegian buyers, sourcing heavy industrial motors from China factories offers a unique blend of technological advancement and cost optimization. Wolong's factories utilize cutting-edge manufacturing equipment, automated stator winding systems, and advanced vacuum pressure impregnation (VPI) facilities.
Every component is engineered to withstand extreme vibrations, corrosion, and continuous duty cycles in demanding marine and mining environments.
Our rotors feature a robust squirrel-cage design. Cast aluminum rotors are manufactured using centrifugal aluminum casting or high-precision die-casting, integrating the rotor bars and end rings into a single, high-durability structure. This ensures outstanding starting torque properties and mechanical stability under high load shocks.
For high-capacity, heavy-duty applications, we construct copper bar rotors using specialized bar-securing and end-ring welding procedures. A protective ring design is applied to high-speed motors to prevent deformation and ensure reliable performance at variable speeds.
The motor coils are crafted with high-purity copper wires, polyester film, and reinforced glass cloth. They are wrapped using high-mica content tape and treated with dynamic Vacuum Pressure Impregnation (VPI). This creates a solid, moisture-resistant winding assembly with excellent heat dissipation.
Our insulation systems meet Class F and Class H standards. They offer high dielectric strength, thermal stability, resistance to environmental moisture, and immunity to acid/alkaline vapors common in industrial environments.
The motor frame is designed using structural and fluid multi-physics simulation platforms. Cast from high-strength iron or structural steel, it features high structural redundancy, excellent heat dissipation pathways, and optimized vibration damping.
This heavy-duty design stands up to mechanical shocks, minimizes vibration levels, keeps shaft alignment precise, and ensures lower temperature rises under continuous operating conditions.
The fan cover system is composed of a light-weight fan cover body, an air guide cylinder, a protective screen, and a silencer plate. The side-entry air inlet bypasses rear obstructions, optimizing ventilation and reducing acoustic energy loss during operation.
Equipped with sound-absorbing materials, the system complies with strict environmental noise regulations. The fan cover is rated IP22, preventing accidental contact with rotating parts while maintaining high airflow rates.
Our motors comply with global explosion-proof, marine, and electrical standards, simplifying authorization and integration at your site.
To support global trade and integration, Wolong maintains a comprehensive set of product certifications:
Nemko / ATEX
CSA Approved
CE Compliance
CCC Certified
SABS Approved
